IMPROVEMENT IN RAILWAY-RAIL JOINTS.

Specification forming part of Letters Patent No. 164,369, dated June 16,1875 application filed November 3, 1874.

To all whom Iit may concern.'

Be it known that I, WORCESTER HADDOCK, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in N ut-Locks; and I do hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying drawings, and to the letters ot' reference marked thereon.

My invention relates to an improvement in device for securing fish-barsat the joints of rail ofrailways; and consists in the use of a key orbolt constructed in two parts, the points ot' which are beveled, and theneck enlarged, as will hereinafter more fully appear.

To enable others skilled in theart to make and use my invention, I willproceed to describe its construction and operation.

In the accompanying drawings, which form part of my specification,Figure l is a perspective view of two sections ot' rails jointed andforming what is known as a ish-joint, the same having my improvement.Fig. 2 is a transverse section of the same. Fig. 3 is a side elevationof the same. Fig. 4. is a side view of my improvement in key or bolt forsecuring the fish-bar B to the rails A.

O represents an ordinary bolt, and D its screw-nut. e represents a thinplate of iron or steel, slightly curved, and provided with a squareopening, adapted in size to the square ofthe nut D. rI he plate c has anopening for the key or bolt j', which is constructed in two parts, andis made of half-round iron, and is furnished with a head, g, with anenlargement in the neck, as shown at h. The points of the key or boltare beveled, as shown at t".

In the operation of inserting the key or boltf in forming the ish-joint,the two dat sides are placed together, and then placed in the openingsof the fish-bars B, rail A, and plate e, as shown in Fig. l. Theoperator then, by means of a suitable tool, bends or spreads the beveledpoints t', as indica-ted in Figs. l and 3, which'will secure theiish-bars B to the rails A, and the plate e to the shbar B, causing oneend of the plate e to be thrown out, so that it will hold the nut D in afixed position on its bolt O.

The skillful operator or railway engineer will readily understand thatthe bolts O and plates e may be dispensed with, and that the ish-bars Bmay be secured to the rails A through the medium of the keys or bolts f.

Oheapness of construction and facility in forming the fish-joint are theadvantages of my improvement.

Having thus described my improvement, what I claim as my invention, anddesire to secure by Letters Patent, is-

A key or bolt for sh-bars for railways, made in two pieces, the pointsof which are beveled and the necks enlarged, substantially as hereindescribed, and for the purposes set forth.
